NOTE: The actual rate of ingress traffic required to activate Storm Control is
based on the actual size of incoming packets and the hard-coded average
packet size (512 bytes) parameter. A packet-per-second rate is calculated,
as the switch requires a pps value to execute or not execute storm control
versus an absolute data rate measured in kilobits-per-second (kbps). For
example, if the configured pps limit for broadcast packets is 10 percent, this
value is converted to approximately 20000 pps for a 100 Mbps port.
Click Apply and then click Close. Your changes are saved to the Running
Configuration.
You can enable port security on a per-port basis. When a port is secured (locked),
the switch forwards only those packets with a source MAC address that is
secured at the port. All other packets are discarded. This includes discarding any
packet from a port with a source MAC address that is secured at another port.
A secure MAC address can be statically configured or dynamically learned. The
maximum number of secure MAC addresses at a secured port is 256. Static
secure MAC addresses are configured using the Static Addresses page. Both
static and dynamic secure MAC addresses are subject to aging limits (see
